I liked using a service called serveo that just uses SSH but recently it went offline so I am back to using either ngrok or localtunnel. These let a remotely-hosted HTTPS domain point to a local port on your computer or server you just request a URL pointing to local port X.

http://serveo.net

https://ngrok.io

https://localtunnel.me

These are command-line tools with NodeJS libraries, you can run them parallel to your project or internally. I am using the NodeJS libraries to create a URL when my tests start. Stripe recently added webhook endpoints to their API so you can also create webhooks bound to whatever URL you are assigned.
